You should read the manga instead. The anime isn't exactly well made. I have only watched up to ep 3 so far, but the anime missed a lot of key dialogues/plots in the original source/manga. Chiron's wish, for example, was hardly explained in the anime. Also Mordred keeps revealing her face unnecessarily, servants revealing their true identity to their opponents like dumb asses (aside from Astolfo they weren't revealed in the manga)
